Question

A quadrilateral has angles that measure 60°, 95°, and 150°.

What is the measure of the fourth angle?

A.
25°

B.
55°

C.
85°

D.
125°

Answer 1

ok so the sum of angles inside a quadrilateral is 360 degrees, so all the angles have to add up to be 360, what does this tell you about the 4th angle?

Answer 2

it need to be equal to 360 also

Answer 3

i gave u a medl also

Answer 4

nope, so what we have is 60+95+150+x=360, so you have to subtract each of those angles from 360 and what you have left is the fourth angle

Answer 5

45

Answer 6

i dont know
